Description

We have multiple bugs related to the timeouts we are hitting on ns_server :-
1) When in swap
2) On windows even on a small cluster.

This bug is to recommend increasing the default timeouts.

We used the following timeouts on most of the params, its not all in one solution, but hopefully would cover basic secnarios.
ns_memcached_outer, 60000
ns_memcached_open_checkpoint, 60000
ns_memcached_outer_heavy, 60000
ns_memcached_outer_very_heavy, 120000
ns_memcached_connected, 10000
ebucketmigrator_connect, 60000

Summary, some error messages and fixes that worked:-
1) Rebalance exited with reason
